CULTIVA'IOR.

- Specification of Letters Patent. Patented Oct. 11, 1910.

Applicationfiled November 9, 1909. Serial No. 526,991.

To all whom it may concern:

Be it known that I, JOHN CHESTER MaxwELL, a citizen of the UnitedStates, residing at Rensselaer, in the county of Jasper and State ofIndiana, have invented certain new and useful Improvements inCultivators; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in cultivator-s.

The object of the invention is to provide a cultivator having animproved construction and arrangement of adjustable Weed destroyingdevices whereby all weeds may be removed close up to the growing plantswithout injuring the same and means to throw the soil back again towardthe plants.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claim.

In the accompanying drawings, Figure 1 is a side view of a cultivatorconstructed in accordance .with my invention; Fig. 2 is a rear view ofthe same; Fig. 3 is a central vertical longitudinal section; Fig. 1- isa horizontal sectional view on the line H of Fig. 2.

1n the embodiment of the invention, I provide a supporting frame whichmay be of the usual or any suitable construction and is here shown andpreferably consists of an arched axle l on the ends of which arerevolubly mounted supporting wheels 2. To the lower ends of the axle 1is secured a rearwardly projecting seat supporting frame 3, on which issecured the drivers seat 4.. To the upper cross bar of the axle issecured the forwardly projecting horizontally disposed tongue supportingframe 5 to which is secured in any suitable manner the draft tongue 6 ofthe machine. To the tongue 6 is connected a whiffie tree 7 on the endsof which are arranged the usual swingle trees 8.

To the central portion of the axle 1 is connected a dependingbeamsupporting frame 9, to the lower laterally projecting ends of whichare secured in any suitable manner the beams 10 of the cultivator. Thebeams 10 are position on the bars constructed at their rear ends in theform of open frames comprising inner longitudinally disposed parallelbars 11 and outer angular or obliquely disposed bars 12 which areconnected directly to the bars 11 at their for- .ward ends and at theirrear ends are con nected to the bars 11 by cross bars 13. The forwardends of the bars 11' of the beam frames are inclined upwardly at theirforward ends and are secured to the tongue in any suitable manner.

In the bars 11 and 12 of the beam frame are formed alined suitablydisposed guiding sleeves 14 in which are slidably and adjustably mountedthe supporting bars 15, said bars being secured in laterally adjustedposition by set screws 16.

On the disk supporting bars 15 are secured inner and outer disk holdingcollars 17, said collars being preferably provided with transverselydisposed passages which are engaged with the bars 15 whereby the collarsare adjustably mounted on the bars. The collars 17 are held in theiradjusted 15 by means of set screws 18, arranged in said collars asshown.

In the collars 17 are adjustably secured the vertically disposed shanks19 of weeding disks 20, which are preferably of circular concavo-convexform. The shanks of the disks 20 are preferably adjustably secured inthe collars 17 by means of set screws 21. By adjustably securing thecollars 17 to the bars 15, said collars may be adjusted laterally tobring the disks nearer to or farther from the rows of plants, thusproviding for the effectual removal of all the weeds up to the rows.

By means of the adjustable connection for the shanks of the disks, thelatter may be turned at any desired angle and "may be raised or loweredto work the ground deeply or shallow, as may be desired.

At the opposite corners of the frame formed by the side bars 11 and 12and the rear cross bars 13 are formed boxes having vertically disposedpassages in which are adjustably secured the shanks 22 of scrapmg orcovering blades 23. The blades 23 are provided to scrape the soil backtoward the rows of plants after the same has been cultivated and theweeds destroyed by the disks 20. By adj ustably securing the shanks ofthe blades 23, the latter may be turned at any suitable angle and may beraised or lowered to the desired elevation.

If desired, the machine may be provided with the usual or any suitableform of raising or lowering levers 25, which are connected to the beamframe in any suitable manner whereby the latter may be lifted up thusraisingthe disks and the blades 23 out of engagement with the ground tofacilitate the removal of the machine from one place to another.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without-requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claim.

Having thus described my invention, what I claim is In a cultivator, amain supporting frame, a pair of laterally spaced approximatelytriangular cultivator frames carried thereby, the side pieces of eachframe having a pair of alined bearing sleeves, disk-supporting barsmounted for endwise adjustment in the bearing sleeves of said cultivatorframes, disk-holding collars mounted for lateral adjustment of saidbars, cultivating disks mounted for angular adjustment in said collarsand a pair of scraping blades mounted for vertical and angularadjustment at the rear end of each of said cultivator frames.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JOHN CHESTER MAXWELL. Witnesses:
